A. oil coking
B. dust accumulation
C. insufficient pressure
D. temperature is too high
Answer: A
Analysis: Coking oil will block the optical path system of the laser welding machine, resulting in a single maintenance cost of more than 500,000 yuan.
Answer: The motor power typically ranges from [C] to [D] kW.
Answer: It offers superior energy efficiency, lower maintenance costs, and a longer lifespan.
Answer: By adopting water lubrication technology, it avoids oil contamination of compressed air and uses an efficient oil-air separation system to ensure the purity of compressed air.
A. Higher B. Lower C. Same as oil injection air compressor D. The answer cannot be determined: B Analysis: Oil-free air compressors usually consume less energy and improve energy efficiency due to reduced use of lubricating oil.
Answer: It adopts an efficient compressor design, optimized system control, and water lubrication technology to reduce energy consumption and improve efficiency.
